Title: Sabots for subcalibre projectiles
IPC: F42B14/06
Filed: 1975-08-21
Abstract: 1513439 Sabot BOFORS AB 21 Aug 1975 [21 Aug 1974] 34818/75 Heading F3A A sabot for a sub-calibre projectile 2 comprises a tubular portion divided by slits 7 into segments 8 and 9, and an annular obturating portion 10 integral therewith, the obturating portion being relatively weak mechanically so that a radially outwardly directed force on the sabot may cause the segments to move outwardly, breaking up the obturating portion. The outwardly directed forces on the sabot may be derived from centrifugal forces or the airflow over the sabot. In the latter case the forward end of the sabot is made concave.

Title: Improvements in or relating to the hardening of iron and steel
IPC: C21D1/58
Filed: 1932-12-08
Abstract: Iron or steel articles are hardened by heating them to red heat (850-950 DEG  C.) in a carbon-dioxide containing atmosphere and then quenching in a bath containing one or more resins or resin soaps and one or more carbon-containing substances dissolved or suspended in one or more oils or fats.  The bath may also contain one or more nitrogen-containing substances and one or more metal compounds such as the metal salts of resin acids, metal formates or carbonyls.  The articles may then be heated and quenched in any known manner.  In an example the bath contains 12 parts of colophony dissolved in 100 parts of linseed oil to which is added 3 part of nickel formate. Instead of or in addition to the formate 7,5 parts of urea may be added.
Patent GB-464302-A (GB)
Title: Manufacture of very thin sheets from polymerised organic compounds
IPC: C08L27/06
Filed: 1935-12-16
Abstract: The process described in the parent Specification is modified in that very thin sheets or films are obtained by rolling a mixed polymerizate from vinyl chloride and one or more acrylic esters of higher aliphatic saturated or unsaturated alcohols containing four or more carbon atoms, on heated rollers in the absence of a solvent. The sheets or films are of a thickness less than 0,1 mm. and may be as thin as 0,03 mm.  Mixed polymerizates from vinyl chloride and a butyl acrylate, or an octyl acrylate, or a mixed polymerizate from vinyl chloride, butyl acrylate, and octodecyl acrylate may be used. A small proportion of methyl or ethyl acrylate may be added to the mixture which is to be polymerized.  Loading material and dyestuffs may be incorporated with the polymerizate.  The films produced may be printed.  They may be used as wrappings, for providing a slippery surface on flat articles, for decorations, for preserving articles made from textiles, paper, cardboard, metal sheets, metal foil such as aluminium or gold foil for cigarette holders.  They may be used as stretched surfaces in aeroplanes.  They may be used in making artificial leather, and in millinery.  The films may be coloured, imprinted, or mat, and artificial flowers may be made therefrom.

Abstract: 1324946 Decorative laminates FUJI KOBUNSHI CO Ltd 26 July 1971 [24 July 1970] 34944/71 Heading B5N A process of producing a decorative board comprises impregnating a decorative paper with a thermosetting resin comprising diallyl phthalate prepolymer or a mixture thereof with an unsaturated polyester and a material for improving the affinity between the paper and the resin which is a prepolymer with an aldehyde of melamine, benzoguanamine, acetoguanamine, urea or polymethyl acrylamide and hot pressing the impregnated paper on to a board. The board may be a veneer board, particle board, hard board or metal. The impregnating agent reduces the formation of minute holes through the paper on hot-pressing and thus keeps the paper watertight. Preferably another piece of paper impregnated with diallyl phthalate resin is placed between the impregnated decorated sheet and the board before hot pressing.

Abstract: 856,429. Transferring vehicles to and from traversers. MITCHELL, F. G. Nov. 21, 1957 [Nov. 22, 1956], No. 35793/56. Class 78 (4). To permit a ram 17 for pushing trucks from a traverser to be retracted when the traverser has been moved from adjacent the ram, the carriage 19 of the ram is supported by an auxiliary track 23 which is moved to an inoperative depressed condition when the traverser is brought up. The auxiliary track 23 may be mounted to be rotated as well as depressed, so that the traverser clears it, or the traverser track 15 may be of such a broad gauge that it is outside the width of the traverser platform so that the auxiliary track may be accommodated between the wheels of the traverser carriage when depressed. In the construction illustrated however the track 15 for the traverser is gapped to receive the auxiliary track 23 when depressed. The track 23 is carried by a platform 20 guided by members 22 and raised and lowered by a ram 21. The Specification describes a system in which valves operated automatically by the movement of a pair of pit cages, a tippler, two traversers, the associated rams, and trucks, provides automatic operation of a pneumatic system for tippling trucks delivered from the pit cages and returning them to the cages. Alternatively, the system may be hydraulic, electro-hydraulic, electro-pneumatic, or electrically operated and the ram may be operated pneumatically, hydraulically, or mechanically.
